Determination of Elemental Carbon and Organic Carbon

This technical report details the methodology for the separation and quantitative determination of elemental carbon (EC) and organic carbon (OC) in ambient air using the multi EA 5100 analyzer. It outlines the importance of accurately measuring these parameters for environmental protection and health, particularly due to the carcinogenic effects of EC. The report describes the automated process employed by the multi EA 5100, which adheres to the VDI 2465-2 standards, emphasizing its efficiency in calibration and processing time. The methodology includes sample preparation, calibration using specially prepared soot standards, and the two-phase measurement process that distinguishes between OC and EC. The results section presents findings from filter samples, demonstrating the system's reliability and performance in quantifying carbon content. The report concludes that the multi EA 5100 provides a fast, reliable, and automated solution for the determination of EC and OC, significantly enhancing sample throughput and reducing operational efforts.
